Radar sen­sor for bulk solids

The Ve­ga­puls 69 sen­sor is a big step closer to the ideal of an all-round radar level mea­sur­ing in­stru­ment for bulk solids.

The level trans­mit­ter op­er­ates at a fre­quency of 79 GHz, which al­lows a con­sid­er­ably bet­ter fo­cus­ing of the t trans­mit­ted sig­nal. In con­tain­ers and si­los w with many in­ter­nal ob­struc­tions, this e en­hanced fo­cus­ing helps re­duce t the in­flu­ence of back­ground ‘noise’. T This means that re­li­able mea­sure­ment i is also pos­si­ble even with com­plex in­ter­nal s struc­tures.

New mi­crowave com­po­nents al­low t the sen­sor to de­tect even the small­est of r re­flected sig­nals. Even prod­ucts, which u un­til re­cently were very dif­fi­cult to mea­sure b be­cause of their poor re­flec­tive prop­er­ties ( (such as plas­tic pow­ders or wood chips) can n now be mea­sured with very high re­li­a­bil­ity.

This con­sid­er­ably ex­tends the ap­pli­ca­tion r range for radar tech­nol­ogy in the bulk s solids in­dus­try and opens up new a ap­pli­ca­tion ar­eas as well.

With a mea­sur­ing range of up to 120 m me­tres and an ac­cu­racy of ±5 mm, t the sen­sor has suf­fi­cient per­for­mance c ca­pa­bil­ity even for the out of the or­di­nary

tasks, such as level gaug­ing in mine shafts or dis­tance mea­sure­ment on con­veyor sys­tems.

De­spite its large mea­sur­ing range, the sen­sor is also an ideal so­lu­tion for small hop­pers or con­tain­ers; the dif­fer­ent antenna de­signs en­able the op­ti­mum so­lu­tion to meet the ap­pli­ca­tion needs.

Com­pletely un­af­fected by dirt and build-up, the lens antenna guar­an­tees main­te­nance­free op­er­a­tion even in harsh en­vi­ron­ments.

To make set-up and com­mis­sion­ing eas­ier, an in­tel­li­gent app for smart­phones has been de­vel­oped. It al­lows quick and easy align­ment of the sen­sor on a swivel holder.
